Serial No. 701,330.

To all whom i'tmcy concern Be it known that I, O'r'ro P. Dnrnnusen, acitizen of the United States, residing at .h/ledford, in the county ofTaylor and State of \Visconsin, have invented new and usefulImprovements in Locks, of which the following is a specification.

This invention relates to the class of locks, and more specifically tothe class of locks which are designed for use in connection with hasps,however, I desire it to be understood that the same can beadvantageously employed in connection with other devices as well.

An object of this invention is to provide a lock which consists of but afew simple parts whereby it can be easily and cheaply manufactured, andone which is durable and cilicient in operation.

With the above and other objects in view, my invention relates to suchdetails of construction and in arrangement and colnbination of theseveral parts as will be hereinafter fully described and specificallypointed out in the appended claims.

In describing my invention in detail, reference will be had to theaccompanying drawings wherein like eha 'acters denote like orcorresponding parts throughout the several views, and in which,

Figure 1 is a front elevation of my improved lock as shown in actualuse. Fig. 2 is a side elevation of the lock, showing a portion of thesame removed. Fi 3 is a similar view. Fig. 4 is a detailed view.

In the accompanying drawings wherein is illustrated the preferred formof my invention, the numeral 1 designates an ordinary hasp which has abracket 2 secured thereon, which bracket has pivotal connection with thelink 3. A slot 4: is provided in the hasp through which slot projects astaple 5 for the purpose obvious.

My invention comprehends casing sections 6, which have off-set portions7 formed thereon and provided with openings 8 for the reception ofsuitable fastening members. Slots 9 are provided in each of thesections, which slots extend vertically in relation thereto and haveoperating thereon pins 10, which are carried by a member 11, the saidmember having its lower end constricted as shown at 12, to formshoulders which provide cam surfaces for the purpose that will behereinafter set forth. For purpose of securing the substantialsemi-circular shackle members 13, links 14L are provided upon the member11 and have pivotal connection with the latch member as shown. It isobvious that when the ends of the shackle means are brought togetherthrough the staple 5 and the member 11 forced downwzu-dly that thedevice will be locked and cannot be opened without the use of a key. Thekey (shown by dotted lines in Fig. 2) is inserted in the keyhole 15formed in one of the casing members and turned to raise the member 11,thereby throwing the shackle member out of engagement with each other.

The greatest of stress is laid upon the simplicity of my invention, andit is thought that the advantages and novel features of the same will bereadily appreciated from the foregoing disclosure.

I desire it to be understood that I may make slight changes in theconstruction and in the arrangement and combination of the severalparts, provided such changes fall within the scope of the sub-joinedclaims.

Having thus fully described my invention what I claim is new and desireto secure by Letters Patent is 2- 1. In a device of the eha 'acterdescribed, a lock comprising casing sections secured together, a memberslidably mounted upon one of said casing sections, an extension formedupon said member and projecting downwardly therefrom and shackle memberspivotally secured to said member for the purpose described.

2. In a device of the character described a lock comprising casingsections rigidly secured together, a member slidably mounted upon one ofsaid casing sections, links carried by said member, shackle memberspivotally secured to said links, an extension depending from said firstmentioned member, whereby said latch members may be closed for thepurpose described.

In a device of the character described, a lock comprising casingsections rigidly secured together, one of said casing sections providedwith spaced apart longitudinally extending slots, a member having pinsinserted therethrough, said pins adapted to en- .gage in said slotswhereby said member is held in slidable engagement thereto, linkscarried by said member, shackle members pivotally secured to said links,and an extension depending from said first mentioned member for thepurpose described.

4. In a device of the character described, a

look comprising casing sections, one of said casing sections providedwithslots, a member having cam surfaces formed on the opposite sidesthereof, pins journaled in said member and projecting into said slots tohold said member in slidable relation to the casing sections, linkscarried by said member, shackle members secured to said links and havingportions adapted to engage said cam surfaces so as to move said-latchmembers into and out of engagement for the purpose set forth.

5. In a device of the character described, a lock comprising sectionsrigidly secured together, each of said members provided With a pluralityof openings for reception of res tening means whereby they may be heldtogether, one of said sections provided With spaced apart longitudinallyextending slots, a member having pins projecting therefrom, said pinsprojecting into said slots whereby said member is held in slidableengagement With said sections, an extension depending from said member,links carried by said member, substantial semi circular latch memberscarried by said links and means for lowering and raising said members soas to move the upper ends of said latch members into and out ofengagement with each other for the purpose described.
